Question

Does the graph represent a function?
Yes Or No

Answer 1

Yes. If you do a vertical line test, you will see that no y values repeat in one x value.

Answer 2

Yes.

Explanation:

First, draw a vertical line. Then check the interception between the graph and a vertical line.

If the line intercepts the graph only one point, then it is a function. Otherwise, it is not. That includes two or more.

The graph shown in the picture is a function (Cubic Function).
